The 180/2.8 AIS ED is a great lens, comparable with the 105/2.5, and a bargain too. As said before, I was looking for a "pocketable" version of the 180, esp. when on a trip with Madame. We had to cancel the 2019 Bretagne trip (touring the four traditional bishoprics:Vannes, Quimper, St Pol de Léon, Tréguier) due to illness, then the same in 2020 due to COVID. So I'm preparing 2021 and it looks like it will be 2022. The envisaged setup is something like 20/2.8 AIS, Voigtländer 58/1.4 and CV 180/4, tucked with the Df in a small Manfrotto messenger bag designed for m43. Still hesitating about the wide angle. Maybe the Zeiss 35/2, especially for night shots. Maybe the 28/3.5 PC, for the fun.
